5. two circular coils of current-carrying wire have the same magnetic moment. the first coil has a radius of , has 140 turns, and carries a current of . the second coil has 170 turns and carries a current of . what is the radius of the second coil?

Answer choices? if there is any

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without it.

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
